Abstract (en)
A method of making an integrally bladed rotor with hollow blades (4). A plurality of segmented layers (9) are sequentially placed to form each one of a plurality of blades (4) on a radially outward surface (3) of a hub (2). This is done using an additive manufacturing process. The placement of the segmented layers (9) also comprises omitting portions of one or more of the plurality of segmented layers (9) to form one or more cavities (7) and intermittently removing a quantity of particles from the one or more cavities (7) using an evacuation tool.
